“You can blow through that quick,” Detroit native Lee (16-3 MMA, 9-3 UFC) told reporters backstage at UFC 218, where he served as a guest fighter and received a hero’s welcome from the crowd. “Ask Floyd Mayweather –Floyd did that about six, seven times.”

Lee has kept tabs on all the McGregor (21-3 MMA, 9-1 UFC) headlines as of late. He thinks the UFC lightweight champ is “(expletive) up” by blowing through cash and allegedly getting into bar fights with mobbed-up characters.

“If the rumors are true, he better get his (expletive) together,” he said. “Because he’s got a long mountain to climb.”

But all the better for Lee. If McGregor tanks, he’ll be waiting to pick up the pieces.

“He’s got Tony (Ferguson) as soon as he comes back,” said Lee, whose title dreams were dashed by Ferguson (24-3 MMA, 14-1 UFC) less than two months ago at UFC 216. “Tony’s going to beat the hell out of him. As soon as he loses that one, I’m going to beat the hell out of him. And then he’s going to be down in the dirt.”

Some think Lee might never get the chance to get over on the Irish champ. This past week, UFC President Dana White reiterated the possibility that McGregor might never fight again after banking $100 million to fight Mayweather in “The Money Fight.”

But Lee said that will only last so long. And the trouble McGregor has created for himself outside of the cage may cause him to seek shelter within it.

“I don’t think he really understands what he’s getting himself, if he’s really messing around with the Irish mob,” Lee said. “I don’t think he’s really from the streets like that. I don’t think he wants none of that smoke.

“But that’s on him. I’m just looking forward to his comeback, and looking forward to taking him out after he gets his ass beat.”
